Answer:

(a) The acceleration of the train and cars is approximately 0.304 m/s²

(b) The tension between the locomotive and the car connected to the locomotive is approximately 0.4166 N

Explanation:

The given parameter are;

The mass of the toy locomotive = 0.979 kg

The mass of one car = 0.952 kg

The mass of the other car = 0.419 kg

The total mass of the train locomotive and cars = 0.979 + 0.952 + 0.419 = 2.35 kg

The weight of the train locomotive and cars = 9.81 m/s² × 2.35 kg = 23.0535 N

The normal force of the train and cars = The weight of the train locomotive and cars = 23.0535 N

The coefficient of dynamic friction = The normal force × The coefficient of dynamic friction

The coefficient of dynamic friction = 23.0535 × 0.110 = 2.535885 N

The applied force = 3.25

The net force acting on the train locomotive and cars = 3.25 - 2.535885 0.714115 N

(a) Force = Mass × Acceleration

Acceleration = Force/Mass

∴ The acceleration of the train and cars = 0.714115 N/(2.35 kg) ≈ 0.304 m/s²

(b) The tension between the locomotive and the car connected to the locomotive = T₂ = ( (m₁ + m₂)/ (m₁ + m₂ + m₃)) × F

Therefore, T₂ =  ( (0.952 + 0.419)/ (0.952 + 0.419 + 0.979)) × 0.714115 ≈ 0.4166 N.

These two forces are called action and reaction forces and are the subject of Newton's third law of motion.

Intrusive igneous bodies refer to rocks that form below the Earth's surface through the cooling and solidification of magma. These bodies are classified based on their size, shape, and geometric relationship with the rocks they intruded into.

One type of intrusive igneous body is a completely crystallized magma chamber, also known as a pluton. These bodies are formed when magma cools slowly and completely within a confined area, resulting in a coarse-grained texture. Another type of intrusive igneous body is a batholith, which is a collection of overlapping plutons. These are massive bodies that can cover an area of hundreds of square kilometers. They are typically formed through the accumulation of magma within the Earth's crust over a long period of time.  A sill is a tabular (sheet-like) igneous body that intrudes parallel to pre-existing layers of rock. These bodies can be several meters to hundreds of meters thick and are formed when magma is injected between layers of rock . Overall, the classification of intrusive igneous bodies helps geologists better understand the geological history of a region.

The answer is b. 16 N.

The tension in the string at the top of the path is 16 N.

At the top of the path, the rock is moving at its highest speed. The tension in the string is providing the centripetal force that keeps the rock moving in a circular path. The centripetal force is equal to the mass of the rock times its velocity squared, divided by the radius of the circle.

F_c = m * v^2 / r

In this case, the mass of the rock is 0.30 kg, the velocity of the rock is 12.0 rad/s, and the radius of the circle is 0.25 m. Substituting these values into the formula above, we get:

F_c = 0.30 kg * (12.0 rad/s)^2 / 0.25 m = 16 N

Therefore, the tension in the string is 16 N.

The factors that affect the flow of electric charge will be Voltage and resistance.

The flow of the charge depends upon the voltage because the voltage is responsible to push or it applies the force on the particles to flow.

For example, whenever your battery gets discharged what happens is the potential difference of voltage becomes zero.

So there will not be enough force remaining in the battery to flow the charge but when we charge the battery then it regains its voltage and again pushes the charges to flow.

Now the resistance acts just opposite to the voltage because it restricts the flow of the charges so if the resistance is more then more voltage is required to flow the charge.

Thus the factors that affect the flow of electric charge will be Voltage and resistance.

Velocity is the speed of an object in a given direction. It is a vector quantity, meaning it has both a magnitude and a direction. It is usually measured in meters per second (m/s). Velocity can also be expressed in other units, such as kilometers per hour (km/h). Velocity is an important concept in physics, and is used to describe the motion of objects in a variety of situations, such as projectiles and waves. It is also used to calculate force, momentum, and energy. In order to calculate velocity, one needs to know both the object's displacement (change in position) and the time it took for the object to move from its starting point to its final position.

The given options, the closest value is 523.60 m^3/s, which corresponds to option (e) 1.31 kg m^2/s.

To find the angular momentum of an object, we can use the formula:

Angular Momentum = Moment of Inertia * Angular Velocity

Given:

Moment of inertia (I) = 5.0 km m^2

Angular velocity (ω) = 5.0 revolutions per minute

First, we need to convert the angular velocity from revolutions per minute to radians per second, as the formula requires angular velocity in radians per second. We know that 1 revolution is equal to 2π radians, and 1 minute is equal to 60 seconds.

Angular velocity (in radians per second) = (5.0 revolutions per minute) * (2π radians per revolution) * (1 minute / 60 seconds)

Angular velocity = (5.0 * 2π) / 60 radians per second

Now we can calculate the angular momentum:

Angular Momentum = Moment of Inertia * Angular Velocity

Angular Momentum = 5.0 km m^2 * [(5.0 * 2π) / 60] radians per second

Simplifying the expression:

Angular Momentum = (5.0 * 5.0 * 2π) / 60 km m^2 radians per second

Angular Momentum = (25 * 2π) / 60 km m^2 radians per second

Angular Momentum = (π/6) km m^2 radians per second

To convert the angular momentum to SI units, we need to multiply by 1000 to convert km to m:

Angular Momentum = (π/6) * 1000 m m^2 radians per second

Angular Momentum = (π/6) * 1000 m^3 radians per second

Simplifying the expression further:

Angular Momentum = (500π/3) m^3 radians per second

To find the answer among the given options, we can calculate the numerical value:

Angular Momentum ≈ 523.60 m^3 radians per second

Among the given options, the closest value is 523.60 m^3/s, which corresponds to option (e) 1.31 kg m^2/s.

According to the question, you would need to add a 40 µF capacitor in order to produce a total capacitance of 50 µF.

What is the capacitor?

An electrical component known as a capacitor stores energy in an electric field. It is made up of two metal plates separated by an insulator, such as air, paper, plastic, or ceramic. When a voltage is applied to the plates, a charge is stored in the electric field. This charge can then be released when the voltage is removed. Capacitors are used in a variety of applications, such as providing energy storage in power supplies, filtering signals in electronic circuits, and providing energy to motors in electrical devices. They can also be used to balance out electrical loads in a circuit, and provide a steady current for the circuit. Capacitors can vary in size, shape, and material depending on the application.

In this case, 90 µF + 40 µF = 130 µF, and 130 µF - 90 µF = 40 µF. Therefore, you would need to add a 40 µF capacitor to the 90 µF capacitor to achieve a total capacitance of 50 µF.
